This is a composite north polar projection map derived from PJ25 images 8 & 14 & 15. Gerald Eichstädt made the individual maps, and I have merged them and enhanced the terminator region. The red cross is the north pole. Four of the circumpolar cyclones (CPCs) are nicely shown; closer to the pole there is an anticyclonic reddish oval; and traces of the central North Polar Cyclone can be seen around the pole itself, although not as regularly as at PJ24. –John Rogers.
